Did Kristen cheat more than once? Joan Rivers drops BIG hint

In her new book Diary of a Mad Diva, Joan Rivers has slammed Kristen Stewart for sleeping her way to the top, hinting that she’s done it more than once.

The fashionista is known for her cruel comments when it comes to what people are wearing, but this is particularly below the belt, even for her!

Rivers wrote:

“Many stars only do one thing well. Of course, the best one-trick pony is Kristen Stewart, who got a whole career by being able to juggle directors’ balls.”

Did we read that correctly, or did Ms. Rivers use “directors’” plural, as in, more than one?

Back in 2012 Kristen was spotted cheating on her then boyfriend Robert Pattinson with director Rupert Sanders on the set of her film Snow White & The Huntsman. However, we thought he was the only one.

Is Joan Rivers hinting that this wasn’t the first occasion that Stewart got cosy with a director?
